摘  要:目的了解男男性行为者(MSM)中HIV感染者性行为状况及影响因素。方法于2010年6—12月采用滚雪球的方法在上海市HIV感染者中招募200例经男男性行为感染者为调查对象,调查其社会人口学特征、艾滋病相关知识、最近6个月男男性行为、异性性行为、饮酒行为、使用烷基亚硝酸盐与毒品行为以及抑郁和焦虑症状,并分析其高危性行为的危险因素。结果共招募200例符合条件者进行调查,45.0%(90/200)调查对象年龄为26~35岁,已婚者、与同性同居和与异性同居的比例分别为30.0%(60/200)、17.0%(34/200)、9.0%(18/200)。57.5%(115/200)的调查对象报告最近6个月有同性肛交行为,13.5%(27/200)的有异性性行为,36.5%(73/200)的拥有2个及以上同性肛交性伴。最近6个月中,与男性发生肛交和女性阴道性交行为时不能坚持每次使用安全套者分别占16.0%(32/200)、3.5%(7/200)。调查对象最近6个月高危性行为(同性无保护肛交或异性无保护阴道性交)报告率为17.5%(35/200)。多因素分析结果显示,高危性行为的危险因素包括:最近1次性行为前饮酒并有醉意(OR=4.270,90%CI:1.676~10.881)、最近6个月在性行为前使用烷基亚硝酸盐(OR:3.397,90%CI:1.564~7.377)、确诊HIV感染时间在半年以内(OR=4.181,90%CI:1.939~9.013)、拥有男性偶然性伴(OR=2.951,90%CI:1.278~5.252)。结论在MSM人群中HIV阳性者存在多性伴和无保护性肛交和阴道交性行为,饮酒及使用烷基亚硝酸盐等物质可增加高危性行为的危险性。Objective To investigate the sexual partners and sexual behaviors among HIV-infected men who have sex with men (MSM) and to examine the factors related with high risky sexual behaviors. Methods A total of 200 HIV-positive MSM participants were recruited using " snowballing" sampling from June to December in 2010 in Shanghai. Participants completed the questionnaire which included social demographic characteristics, sexual behaviors with male and female sexual partners in the past 6 months, alcohol consumption, alkyl nitrite use, illegal substances use and depression and anxiety symptoms, etc. Results Of the 200 HIV-positive MSM participants, 45.0% (90/200) of participants' ages ranged from 26 to 35, and 30. 0% (60/200) of the respondents were married. Participants living with a male partner and living with a female partner accounted for 17.0% (34/200) and 9.0% (18/200), respectively. A total of 57.5% (115/200) had anal sex with male and 13.5% (27/200) had sex with female in the past 6 months. The percentage of participants who had 2 or more male anal sexual partners was 36.5% (73/200). During last six months, participants who didn't use condom consistently during anal sexes with men and vaginal sexes with women accounted for 16.0% (32/200) and 3.5% (7/200), respectively. The rate of risky sexual behaviors (any unprotected sex with male or female) during past 6 months was 17.5% (35/200). Factors associated with risky sexual behaviors included getting drunk before last sex (OR =4. 270,90% CI: 1. 676 - I0. 881 ) , using alkyl nitrite ( OR = 3. 397, 90% CI: 1. 564 - 7. 377 ) and having casual male partners( OR = 2. 951,90% CI: 1. 278 - 5. 252) during past six months, getting HIV infection diagnosis in half year ( OR = 4. 181,90% CI: 1. 939 - 9. 013 ) .
